Below, an embodiment of the present invention is described with reference to the attached drawings.

First Embodiment
A hydrogen generating device 1 in a first embodiment of the present invention will be described with reference to Fig. 1. The hydrogen generating device 1 in this embodiment includes a container portion 10, a hydrogen generating agent packaging body 20, and a movement restricting portion 30. In Figs. 1(A) and 1(B), the hydrogen generating device 1 is packaged in an outer packaging body 40. In this specification, the hydrogen generating device 1 packaged in the outer packaging body 40 will also be referred to as the hydrogen generating device 1 as appropriate.

<Container>
As shown in Figs. 1A and 1B, the container 10 is formed in a bottomed cylindrical shape with an opening 11 provided on one side in the depth direction of the container 10 and the other side in the depth direction of the container 10 being closed. The container 10 has an internal space 10A inside that communicates with the outside through the opening 11. Specifically, the container 10 has, for example, a truncated cone shape, and has a bottom wall 12 (bottom part) and a peripheral wall 14. The bottom wall 12 (bottom part) is provided on the bottom side where the diameter of the truncated cone shape is small. The container 10 has an opening 11 on the bottom side where the diameter of the truncated cone shape is large.

The peripheral wall 14 is an annular wall that starts from the outer edge of the bottom wall 12 and extends in a vertical direction having a component A in the axial direction of the container portion 10 (hereinafter referred to as the container axial direction). The container axial direction A is parallel to the depth direction of the container portion 10. The peripheral wall 14 is formed in a tapered shape that inclines so as to expand radially outward as it advances along the container axial direction A toward the opening 11. Therefore, the peripheral wall 14 is inclined with respect to the container axial direction A. The peripheral wall 14 also has a peripheral wall piece 14E (corresponding to the base wall 16 in the eighth embodiment described later) that starts from the outer edge of the bottom wall 12 and extends to the opposite side of the opening 11.

The container 10 may be made of, for example, paper, polyethylene (PE), polystyrene (PS), polypropylene (PP), polyethylene terephthalate (PET), etc. That is, the container 10 may be, for example, a paper cup or a plastic cup. The container 10 may also be made partially or entirely of a transparent material (see the window in the thirteenth embodiment described below).

It is also preferable that the inner bottom surface 12A of the bottom wall 12 of the container portion 10 is provided with a moisture barrier layer 13 made of a material that blocks moisture or does not allow moisture to pass through. An example of a moisture barrier material is aluminum, but this is not limited to this and other materials may be used. The moisture barrier layer 13 is provided by evaporating aluminum onto the inner bottom surface 12A of the container portion 10. When the moisture barrier layer 13 is provided, the surface of the moisture barrier layer 13 corresponds to the inner bottom surface 12A.

<Hydrogen generating agent packaging>
The hydrogen generating agent package 20 will be described with reference to FIG. 2. As shown in FIG. 2B, the hydrogen generating agent package 20 is formed in a bag shape and contains a hydrogen generating agent 21. The hydrogen generating agent package 20 is independent of the container 10 and can be easily inserted and removed from the container 10. That is, when the hydrogen generating agent package 20 is contained in the container 10, the hydrogen generating agent 21 is contained in the container 10. The hydrogen generating agent 21 generates hydrogen in response to a liquid such as water. The material of the hydrogen generating agent 21 may be, for example, a mixture of aluminum (Al) and calcium oxide (CaO), but is not limited thereto, and may be any other material that generates hydrogen in response to a liquid. An example of calcium oxide (CaO) is powdered quicklime. Aluminum (Al) is used, for example, in a powder form. That is, it is preferable that both aluminum (Al) and calcium oxide (CaO) are powdered. The hydrogen generating agent 21 configured as above reacts with water to generate hydrogen. The liquid is not limited to water. The liquid includes all kinds of liquids that react with the hydrogen generating agent 21 to generate hydrogen.

2(A) and (B), the hydrogen generating agent 21 is housed in a bag body 23 having a bag mouth 22, for example. The bag body 23 has a lid piece 24 that closes the bag mouth 22. The lid piece 24 is a portion that extends from the bag body main body 25 in the length direction of the bag body 23 starting from the bag mouth 22. The bag body 25 may be provided with a gusset 25A so that the thickness of the bag body 25 is increased. The hydrogen generating agent 21 is packed inside the bag body 25 through the bag mouth 22. When a predetermined amount of the hydrogen generating agent 21 is packed inside the bag body 25, the lid piece 24 is placed over the bag mouth 22 to close the bag mouth 22.

In addition to the hydrogen generating agent 21, the bag 23 may also contain an aromatic agent containing a fragrance component. Examples of aromatic agents include those containing coffee bean components, those containing vanilla components, and those containing fruit fragrance components such as strawberry, but are not limited to these and include all other aromatic agents. This allows the hydrogen generating device 1 in this embodiment to generate not only hydrogen but also fragrance components. As a result, the user of the hydrogen generating device 1 can inhale hydrogen without getting bored. However, the aromatic agent must not lose its fragrance when liquid is poured into it.

The aromatic agent may not be contained in the bag 23, but may be included in the hydrogen generating liquid that is poured into the hydrogen generating agent 21 later. The aromatic agent may also be added to the liquid later. Even in this case, the hydrogen generating device 1 can generate not only hydrogen but also aromatic components in the same manner as described above.

The bag 23 (bag body 25) is provided with a plurality of fine air holes. The plurality of fine air holes are preferably of a size that allows the liquid used in hydrogen generation and the hydrogen-containing gas generated from the hydrogen generating agent 21 to pass through, but does not allow the hydrogen generating agent 21 or the aromatic agent itself to pass through. The bag 23 may be a braided body made of fibers. In this case, the mesh of the braided body corresponds to the fine air holes. The bag 23 (bag body 25) may also be formed from a nonwoven fabric.

<Movement restriction section>
The movement limiting part 30 will be described with reference to Figs. 3 to 5. The movement limiting part 30 limits the movement range of the hydrogen generating agent package 20 inside the container part 10. In this embodiment, the hydrogen generating agent package 20 is placed on the inner bottom surface 12A of the container part 10 as shown in Fig. 3(A). Then, the movement limiting part 30 is composed of a package fixing part 31 that fixes the hydrogen generating agent package 20 to the inner bottom surface 12A of the container part 10 so that the hydrogen generating agent package 20 does not rise to the water surface when the liquid 100 is poured into the container part 10 as shown in Fig. 3(B). If the movement range of the hydrogen generating agent package 20 is within a range in which the entire hydrogen generating agent package 20 can come into contact with the liquid, the entire hydrogen generating agent package 20 is always cooled by the liquid. Therefore, even if the hydrogen generating agent 21 generates heat when reacting with the liquid, the temperature of the container part 10 can be reduced. As a result, the user of the hydrogen generating device 1 does not feel hot when holding the container part 10.

In this embodiment, the hydrogen generating agent package 20 has a belt-shaped region 26 and a main region 27, as shown in FIG. 3(C). The belt-shaped region 26 extends along the side 20C of the hydrogen generating agent package 20 on the bag mouth 22 side in the vicinity of the side 20C. In this embodiment, the side 20C on the bag mouth 22 side extends in an approximately straight line. In this embodiment, the belt-shaped region 26 extends only along a portion of the side 20C, but is not limited to this and may extend along the entire length of the side 20C. In this embodiment, the width of the width direction B of the belt-shaped region 26 is preferably 1/3 or less of the total length in the length direction C of the hydrogen generating agent package 20 parallel to the width direction B, more preferably 1/4 or less of the total length, and even more preferably 1/5 or less of the total length. The main region 27 is the main part of the hydrogen generating agent package 20, and is continuous with the belt-shaped region 26 on the longitudinal side of the belt-shaped region 26.

As shown in FIG. 3B, the packaging body fixing part 31 fixes the belt-shaped surface 26A on one side of the belt-shaped region 26 to the inside bottom surface 12A of the container part 10. The packaging body fixing part 31 may be fixed, for example, by glue, double-sided tape, or heat fusion. This allows the main region 27 to move around the boundary between the belt-shaped region 26 and the main region 27 as an axis. In other words, when liquid 100 is poured into the container part 10, the main region 27 can rise up so as to sway (swirl) around the boundary with the belt-shaped region 26 as an axis. At this time, the main region 27 can take a position inclined with respect to the inside bottom surface 12A as shown in FIG. 3B. In this state, the liquid 100 contacts the main region 27 from both the front surface 27A side and the back surface 27B side. Therefore, the liquid 100 contacts the hydrogen generating agent 21 efficiently, and hydrogen is generated efficiently.

As shown in Fig. 4(A), the packaging fixing part 31 may fix the hydrogen generating agent packaging body 20 to the inner bottom surface 12A of the container part 10 so that the hydrogen generating agent packaging body 20 cannot move even when liquid 100 is poured into the container part 10. In this case, as shown in Fig. 4(B), the packaging fixing part 31 may fix a region R that extends from the central region of the hydrogen generating agent packaging body 20 toward the outer edge of the hydrogen generating agent packaging body 20 to the inner bottom surface 12A of the container part 10. As shown in Fig. 4(B), the region R may be substantially the entire region of the hydrogen generating agent packaging body 20.

4(C), the package fixing portion 31 may fix a portion of the interior of each of the four divided regions, which are obtained by dividing the entire region of the hydrogen generating agent package 20 equally into four regions, and a portion of the central region of the hydrogen generating agent package 20, to the inner bottom surface 12A of the container portion 10. Note that the divided regions are not limited to being divided into four regions, and may be divided into any other number of regions. Also, a portion of the central region may not be fixed by the package fixing portion 31.

<Modifications of the packaging body fixing part>
5(A) to (F), modified examples of the packaging body fixing part 31 will be described. As shown in Fig. 5(A), the packaging body fixing part 31 may be configured to press the band-shaped region 26 of the hydrogen generating agent packaging 20 against the inner bottom surface 12A of the container part 10. In this case, the packaging body fixing part 31 has, for example, a base part 390 fixed to the inner bottom surface 12A, and a pressing part 391.

The base 390 is fixed to the inner bottom surface 12A of the container 10. The pressing portion 391 extends in a strip shape from one end of the base 390. As shown in FIG. 5(C), in the initial state in which no external force is applied, the pressing portion 391 abuts against the inner bottom surface 12A or takes a posture approximately parallel to the inner bottom surface 12A of the container 10 in the vicinity of the inner bottom surface 12A. Also, as shown in FIG. 5(B), the pressing portion 391 can rotate in a direction approaching or receding from the inner bottom surface 12A of the container 10, with the boundary line 393 with the base 390 as an axis. And, even if the pressing portion 391 is rotated in a direction receding from the inner bottom surface 12A of the container 10, it operates to return to the initial state by the elastic force at the boundary portion with the base 390. 5A, the pressing portion 391 is preferably provided with a hole 392 penetrating in the container axial direction A. At least one hole 392 may be provided.

As shown in Fig. 5(D), the package fixing portion 31 may have, for example, two base portions 390 fixed to the inner bottom surface 12A and a pressing portion 391. The two base portions 390 are connected to both ends of the pressing portion 391.

Even in the above cases, the band region 26 of the hydrogen generating agent packaging body 20 is fixed to the inner bottom surface 12A of the container portion 10. The main region 27 of the hydrogen generating agent packaging body 20 is then able to pivot about the boundary with the band region 26 of the hydrogen generating agent packaging body 20 as an axis.

As shown in FIG. 5(E), the packaging body fixing portion 31 may be configured to press the band-like region 26 and the main region 27 of the hydrogen generating agent packaging body 20 against the inner bottom surface 12A of the container portion 10. The packaging body fixing portion 31 may be similar to that described above with reference to FIGS. 5(B) to (D). Also, as shown in FIG. 5(F), the packaging body fixing portion 31 may be configured to press the four corners of the hydrogen generating agent packaging body 20 against the inner bottom surface 12A of the container portion 10. This packaging body fixing portion 31 is similar to that described above with reference to FIGS. 5(B) to (D), except that the length of the pressing portion 391 is shortened.

<External packaging body>
The external packaging body 40 will be described with reference to Fig. 1. The external packaging body 40 encases the hydrogen generating agent packaging body 20, the movement restriction section 30 and the container section 10 so as to prevent dust and the like from adhering to the inside and outside of the container section 10. In other words, the external packaging body 40 encases the entire hydrogen generating device 1. In this embodiment, the external packaging body 40 is composed of, for example, a transparent or colored film. Examples of the material of the transparent or colored film include, for example, polyethylene, polypropylene, polyamide, polyethylene terephthalate, etc., but are not limited thereto, and other materials may be used.

1(A) and (B), the outer packaging body 40 is packaged so as to be in close contact with the outer peripheral surface 14A of the peripheral wall 14 of the container portion 10, the outer bottom surface 12B of the bottom wall 12, the inner peripheral surface 14B of the container portion 10, the inner bottom surface 12A of the bottom wall 12, and the hydrogen generating agent packaging body 20. In this embodiment, the movement limiting portion 30 is located between the inner bottom surface 12A of the bottom wall 12 and the hydrogen generating agent packaging body 20, so the outer packaging body 40 does not come into close contact with the movement limiting portion 30. However, in other embodiments described later, the outer packaging body 40 may come into close contact with the movement limiting portion 30.

As shown in FIG. 1(B), the outer packaging body 40 is preferably provided with a moisture barrier layer 41 made of a moisture-blocking material in a portion facing the hydrogen generating agent packaging body 20 in the container axial direction A. If the moisture barrier layer 41 is provided, the hydrogen generating agent packaging body 20 can be protected from moisture.

Second Embodiment
The hydrogen generating device 1 in the second embodiment of the present invention will be described with reference to Fig. 6. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent package 20, and outer package 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the first embodiment of the present invention in the configuration of the movement restriction portion 30.

6(A) and (B), the movement restriction portion 30 in this embodiment has a string portion 32 and a string side fixing portion 33. The string portion 32 is a string-shaped portion, and one end is connected to the hydrogen generating agent packaging body 20. Examples of the string portion 32 include, but are not limited to, a fiber thread or a resin thread, and may be made of other materials.

The string side fixing part 33 fixes the string part 32 inside the container part. In this embodiment, the string side fixing part 33 has an intermediate member 33A and an intermediate member side fixing part 33B. The intermediate member 33A is, for example, a sheet-like member. The other end of the string part 32 is connected to the intermediate member 33A. The intermediate member side fixing part 33B fixes the intermediate member 33A to the inner bottom surface 12A of the container part 10. The intermediate member side fixing part 33B may be fixed, for example, by glue, double-sided tape, or heat fusion.

That is, the movement limiting section 30 in this embodiment allows the hydrogen generating agent package 20 to move inside the container 10 in accordance with the trajectory of one end of the string 32 when the connection between the other end of the string 32 and the intermediate member 33A is used as a fulcrum, but restricts other movements. Therefore, in the case of the movement limiting section 30 in this embodiment, when the liquid 100 is poured into the container 10, as shown in FIG. 6(B), the hydrogen generating agent package 20 is restricted to a range of movement in accordance with the trajectory of the other end of the string 32.

6(C) and (D), two string portions 32 may be provided. In this case, for example, one string portion 32 is connected near the bag mouth 22 of the hydrogen generating agent packaging body 20, and the other end of the other string portion 32 is connected near the bag bottom 28 of the hydrogen generating agent packaging body 20. At this time, one string portion 32 is fixed to the inner bottom surface 12A of the container portion 10 by an intermediate member side fixing portion 33B (e.g., glue, double-sided tape, etc.) through an intermediate member 33A. The other string portion 32 is directly fixed to the inner bottom surface 12A of the container portion 10 by the string side fixing portion 33.

The movement restriction section 30 allows the hydrogen generating agent package 20 to move inside the container 10 according to the trajectory of the other end of one of the string sections 32 when the connection between one end of the one string section 32 and the intermediate member 33A is used as a fulcrum, and according to the trajectory of the other end of the string section 32 when the connection between one end of the other string section 32 and the inner bottom surface 12A is used as a fulcrum, but restricts other movements. Therefore, in the case of the movement restriction section 30, when liquid 100 is poured into the container 10, as shown in FIG. 6(D), the hydrogen generating agent package 20 is restricted to a movement range according to the trajectories of the other ends of the two string sections 32.

Third Embodiment
The hydrogen generating device 1 in the third embodiment of the present invention will be described with reference to Fig. 7. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent package 20, and outer package 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the first and second embodiments of the present invention in the configuration of the movement restriction portion 30.

7A and 7B, the movement restriction section 30 in this embodiment is configured by a storage chamber 34 provided inside the container section 10. The storage chamber 34 has an internal storage space 34A capable of storing the hydrogen generating agent package 20. The storage chamber 34 is configured by a partition wall 35 and a storage chamber component part 10B of the container section 10 that is lower than the partition wall 35 in the container axial direction A. The storage chamber component part 10B is configured by the bottom wall 12 of the container section 10 and a peripheral wall piece 14D of the container section 10 that is lower than the partition wall 35 in the container axial direction A.

As shown in FIG. 7(A), the partition wall 35 is, for example, disk-shaped. As shown in FIG. 7(B), the partition wall 35 divides the internal space 10A of the container part 10 in the container axis direction A. The partition wall 35 is preferably provided at least below the central part of the container part 10 in the container axis direction A, but is not limited thereto, and may be provided above the central part of the container part 10 in the container axis direction A. In this embodiment, the partition wall side facing surface 35C of the partition wall 35 facing the internal bottom surface 12A of the container part 10 is parallel to the internal bottom surface 12A, but is not limited thereto, and may not be parallel.

It is preferable that a moisture barrier layer 36 made of a moisture-blocking material is provided on the partition wall side facing surface 35C. This is to block moisture from reaching the hydrogen generating agent package 20 contained in the storage chamber 34.

In addition, a vent hole (which may be called a storage chamber side vent hole; the same applies below) 35A is provided in the center of the partition wall 35, penetrating in the container axial direction A. Hydrogen generated from the hydrogen generating agent package 20 passes through the vent hole 35A and rises toward the opening 11. At least one vent hole (which may be called a storage chamber side vent hole; the same applies below) 35B penetrating the partition wall 35 in the container axial direction A may be provided around the vent hole 35A. This is to smoothly guide the hydrogen generated from the hydrogen generating agent package 20 to the opening 11. In this embodiment, eight vent holes 35B are provided. The storage space 34A of the storage chamber 34 and the internal space 10A of the container part 10 are connected through the vent holes 35A and 35B.

According to the hydrogen generating device 1 in this embodiment, when liquid 100 is poured into the container portion 10, the hydrogen generating agent packaging body 20 becomes movable within the storage space 34A of the storage chamber 34.

<First Variation of the Containment Chamber>
A first modified example of the storage chamber 34 will be described with reference to Figures 8(A) and (B). As shown in Figure 8(A), the first modified example of the storage chamber 34 is configured by a storage chamber component 340 and a bottom wall 12. As shown in Figures 8(A) and (B), the storage chamber component 340 has a cylindrical shape with a bottom. Specifically, the storage chamber component 340 has a partition wall 341 and a peripheral wall 342.

When the storage chamber component 340 is installed on the inner bottom surface 12A of the container portion 10, the partition wall 341 becomes similar to the partition wall 35 described above, and therefore a description thereof will be omitted. The peripheral wall 342 is inclined from the outer edge of the partition wall 341 as it approaches the central axis of the storage chamber component 340 as it proceeds downward in the container axial direction A, and has a cylindrical shape resembling a truncated cone. Note that the above-described shape of the peripheral wall 342 is made to match the shape of the inner side of the container portion 10, and if the shape of the inner side of the container portion 10 is a shape other than a truncated cone, it is preferable that the peripheral wall 342 have a shape corresponding to that shape.

When the storage chamber component 340 is placed on the inner bottom surface 12A of the container 10, the storage chamber 34 is formed by the storage chamber component 340 and the bottom wall 12. In order to prevent the storage chamber component 340 from floating up when the liquid 100 is poured into the container 10, it is preferable that the storage chamber component 340 has a shape and size that fits into the container 10 near the inner bottom surface 12A of the container 10. In addition, the storage chamber component 340 may be in a state of contacting and fixed to the inner bottom surface 12A of the container 10 or the inner peripheral surface 14B of the container 10. In this case, the bottom surface 342A of the peripheral wall 342 may be fixed to the inner bottom surface 12A of the container 10, or the outer peripheral surface 342B of the peripheral wall 342 may be fixed to the inner peripheral surface 14B of the container 10. Additionally, the storage chamber component 340 may be configured to have a weight such that it does not float on liquid.

<Second modified example of the containment chamber>
A second modified example of the storage chamber 34 will be described with reference to Figs. 8C and 8D. The second modified example of the storage chamber 34 is configured by a storage chamber component 343 as shown in Fig. 8C. The storage chamber component 343 has a hollow cylindrical shape as shown in Figs. 8C and 8D. Specifically, the storage chamber component 343 has a ceiling wall 344, a peripheral wall 345, and a bottom wall 346. The ceiling wall 344 corresponds to the ceiling portion of the storage chamber component 343. When the storage chamber component 343 is installed on the inner bottom surface 12A of the container 10, the ceiling wall 344 becomes substantially the same as the partition wall 35 described above, and therefore a description thereof will be omitted.

The bottom wall 346 corresponds to the bottom portion of the storage chamber component 343. When the storage chamber component 343 is installed on the inner bottom surface 12A of the container portion 10, the bottom wall 346 abuts against the inner bottom surface 12A.

The peripheral wall 345 extends downward in the container axial direction A from the outer edge of the ceiling wall 344 to the outer edge of the bottom wall 346. The peripheral wall 345 is inclined so as to approach the central axis of the storage chamber component 340 as it progresses downward in the container axial direction A, and has a cylindrical shape resembling a truncated cone. Note that the above-described shape of the peripheral wall 345 is made to match the shape of the interior side of the container portion 10, and if the shape of the interior side of the container portion 10 is a shape other than a truncated cone, it is preferable that the peripheral wall 345 have a shape corresponding to that.

The peripheral wall 345 may also be provided with an insertion opening 347 for inserting the hydrogen generating agent packaging 20 into the storage space 34A. When the storage chamber component 343 is installed inside the container portion 10, the insertion opening 347 is preferably configured to be blocked by the inner peripheral surface 14B of the container portion 10. Even if the insertion opening 347 is configured not to be blocked by the inner peripheral surface 14B of the container portion 10, the distance between the insertion opening 347 and the inner peripheral surface 14B is small compared to the size of the hydrogen generating agent packaging 20, so that the hydrogen generating agent packaging 20 does not protrude outside the storage chamber component 343 through the insertion opening 347.

When the storage chamber component 343 is placed on the inner bottom surface 12A of the container 10, the storage chamber component 343 forms the storage chamber 34. Note that in order to prevent the storage chamber component 343 from floating up when the liquid 100 is poured into the container 10, the storage chamber component 343 may be configured in the same manner as the storage chamber component 340 in this respect.

<Fourth embodiment>
The hydrogen generator 1 in the fourth embodiment of the present invention will be described with reference to Fig. 9. The hydrogen generator 1 in this embodiment has the same container 10, hydrogen generating agent package 20, and outer package 40 as the hydrogen generator 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generator 1 in this embodiment differs from the hydrogen generators 1 in the other embodiments in the configuration of the movement restriction portion 30.

The movement restriction section 30 in this embodiment is composed of a pressing member 37. In this embodiment, the pressing member 37 has the same shape as the container section 10 as shown in Figures 9 (A) and (B) and is sized to be insertable into the container section 10. The pressing member 37 presses the hydrogen generating agent package 20 placed on the inner bottom surface 12A from above in the container axial direction A. As shown in Figure 9 (A), the pressing member 37 has, for example, a pressing side bottom wall 370 and a pressing side peripheral wall 371.

As shown in Fig. 9(B), the pressing-side bottom wall 370 is a portion that contacts the hydrogen generating agent package 20 placed on the inner bottom surface 12A. The pressing-side peripheral wall 371 is a tapered cylindrical (annular) wall that starts from the outer edge of the pressing-side bottom wall 370 and slopes away from the central axis of the pressing member 37 as it progresses upward in the container axial direction A, forming a truncated conical cylindrical shape.

In addition, it is preferable that a detachable attachment mechanism 372 is provided between the outer periphery of the pressing-side peripheral wall 371 and the inner periphery of the peripheral wall 14 of the container part 10. The attachment mechanism 372 is composed of, for example, an annular rib 371A that goes around the outer periphery of the pressing-side peripheral wall 371, and a fitting groove 14C that is provided on the inner periphery of the peripheral wall 14 at a position proximate to the opening 11 of the container part 10.

The rib 371A is formed of a convex portion that protrudes radially outward from the outer side of the pressing side peripheral wall 371. The rib 371A is annular, going around the outer periphery of the pressing side peripheral wall 371. The fitting groove 14C is formed of a concave portion that protrudes radially outward from the inner periphery of the peripheral wall 14. The shape of the concave portion corresponds to the shape of the convex portion of the rib 371A.

When the pressing-side peripheral wall 371 is inserted into the container 10, the rib 371A is elastically deformed to fit into the fitting groove 14C. When the pressing-side peripheral wall 371 is pulled out, the rib 371A is elastically deformed to come out of the fitting groove 14C.

<Modifications of the pressing side peripheral wall>
9C and 9D, a band-shaped wall 374 which is a modified example of the pressing-side peripheral wall 371 will be described. The pressing-side peripheral wall 371 may be replaced with the band-shaped wall 374. Unlike the above, the band-shaped wall 374 is not cylindrical (annular) but band-shaped.

The attachment mechanism 372 is composed of a hook portion 375 and the peripheral wall 14 near the opening 11 of the container portion 10. The hook portion 375 is provided on the upper end of the belt-shaped wall 374. The hook portion 375 is a portion shaped so that it can be hooked onto the peripheral wall 14. The hook portion 375 is formed, for example, in a U-shape.

In the first to fourth embodiments, the hydrogen generating agent package 20 is placed on the inner bottom surface 12A of the container 10, but the present invention is not limited to this. The hydrogen generating agent package 20 may be placed in contact with the inner circumferential surface 14B of the container 10. However, when a large number of hydrogen generating devices 1 are transported by a transporter, it is assumed that a plurality of hydrogen generating devices 1 are stacked so that the container 10 is inserted into the inner space 10A of another container 10 through the opening 11. In the case where the hydrogen generating agent package 20 is placed in contact with the inner circumferential surface 14B of the container 10, the peripheral wall 14 is substantially thicker by the hydrogen generating agent package 20. When such hydrogen generating devices 1 are stacked as described above, the inserted hydrogen generating device 1 may be deformed, which reduces the commercial value. From this viewpoint, the hydrogen generating agent package 20 is preferably placed on the inner bottom surface 12A of the container 10. This is also true in the seventh embodiment described below.

Fifth Embodiment
The hydrogen generating device 1 in the fifth embodiment of the present invention will be described with reference to Figures 10 to 13 and 27. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent packaging body 20, and outer packaging body 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the other embodiments in the configuration of the movement restriction portion 30.

As shown in Figures 10(A) and (B), the movement restriction section 30 is composed of an extension section 38 that extends from the opening 11 of the container section 10 toward the inner bottom surface 12A of the container section 10. The hydrogen generating agent packaging body 20 is provided at one end of the extension section 38 or in its vicinity. A hook section 380 is provided at the other end of the extension section 38 or in its vicinity. The extension section 38 may be rod-shaped, band-shaped, or any other shape.

10(A) and (B), the extension portion 38 is attached to the container portion 10 by an attachment mechanism 381. The attachment mechanism 381 is similar to the attachment mechanism 372 described in the above <Modification of the pressing side peripheral wall>, so its description is omitted.

It is preferable that the extension portion 38 has a length that allows the extension portion 38 or the hydrogen generating agent package 20 to abut against the inner bottom surface 12A of the container portion 10 when the hook portion 380 is hooked onto the upper end of the peripheral wall 14 of the container portion 10. This is to prevent the hydrogen generating agent package 20 from moving freely within the container portion 10 by the extension portion 38 or the hydrogen generating agent package 20 abutting against the inner bottom surface 12A of the container portion 10. The extension portion 38 has a configuration similar to that of the band-shaped wall 374 in the fourth embodiment.

The extension portion 38 holds the hydrogen generating agent package 20 in various ways. For example, in a band-shaped extension portion 38 provided with a through hole 382 as shown in FIG. 11(A), the hydrogen generating agent package 20 is inserted into the through hole 382 as shown in FIG. 12(A) so that the extension portion 38 holds the hydrogen generating agent package 20. The through hole 382 penetrates the extension portion 38 in the thickness direction of the extension portion 38. The through hole 382 is a vertically elongated hole formed in a band shape, and is provided on the opposite side of the hook portion 380 in the length direction of the extension portion 38 and in the center of the width direction of the extension portion 38. The width of the through hole 382 in the width direction is approximately the same as or smaller than the thickness of the hydrogen generating agent package 20. The extension portion 38 is made of an elastically deformable material. As shown in FIG. 12(A), when the hydrogen generating agent packaging body 20 is inserted into the through hole 382, it presses the strip pieces 383A, 383B located on either side of the through hole 382 in the width direction outward in the width direction, and is held by the extension portion 38 by being clamped by the strip pieces 383A, 383B due to the reaction force.

The through hole 382 may be formed by a slit. The slit width is smaller than the thickness of the hydrogen generating agent packaging 20. If the extension portion 38 is formed from an elastically deformable material, the hydrogen generating agent packaging 20 presses the strip pieces 383A, 383B located on both sides of the slit in the width direction outward in the width direction, and the strip pieces 383A, 383B are clamped by the reaction force and held by the extension portion 38.

For example, in a band-shaped extension portion 38 provided with a slit 384 as shown in Fig. 11(B), the hydrogen generating agent package 20 is inserted into the slit 384 as shown in Fig. 12(B) so that the extension portion 38 holds the hydrogen generating agent package 20. The slit 384 starts at the end of the extension portion 38 opposite the hook portion 380 in the longitudinal direction, and extends halfway along the extension portion 38. The length of the slit 384 may be greater or less than the longitudinal length of the hydrogen generating agent package 20. The extension portion 38 is made of an elastically deformable material. When the hydrogen generating agent packaging body 20 is inserted into the slit 384, as shown in FIG. 12 (B), the hydrogen generating agent packaging body 20 presses the strip pieces 385A, 385B located on either side of the slit 384 outward in the width direction, and is held by the extension portion 38 by being clamped by the strip pieces 385A, 385B due to the reaction force.

For example, in a band-shaped extension portion 38 provided with a clamping mechanism 386 as shown in FIG. 11(C), as shown in FIG. 12(C), the hydrogen generating agent package 20 is inserted into the clamping mechanism 386, and the extension portion 38 holds the hydrogen generating agent package 20. The clamping mechanism 386 has band-shaped pieces 387A and 387B. The band-shaped piece 387A constitutes one section in the longitudinal direction of the extension portion 38. Specifically, the band-shaped piece 387A constitutes a section from the middle of the extension portion 38 to the end of the extension portion 38 on the opposite side to the hook portion 380 in the longitudinal direction or in the vicinity just before the end. The band-shaped piece 387B is arranged in parallel with the band-shaped piece 387A in the thickness direction of the extension portion 38. The two longitudinal ends of the band-shaped piece 387B are connected to the two longitudinal ends of the band-shaped piece 387A.

The strips 387A and 387A are configured so that the space between them can be pushed apart. In this case, the strips 387A and 387A are made of an elastically deformable material. Alternatively, the strips 387A and 387A are configured so that at least one of the strips has some play in length so that a gap is formed between the strips 387A and 387A into which the hydrogen generating agent package 20 can be inserted.

When the hydrogen generating agent packaging body 20 is inserted into the clamping mechanism 386, as shown in FIG. 12 (C), the band pieces 387A, 387B are pressed outward in the width direction, and the hydrogen generating agent packaging body 20 is held by the extension portion 38 by being clamped by the band pieces 387A, 387B due to the reaction force.

13(A), the hook portion 380 may be configured to have a clamping portion 380A in which the distance of the U-shaped gap in the hook portion 380 is approximately the same as or slightly smaller than the thickness of the upper end portion of the peripheral wall 14 of the container portion 10. In this case, the clamping portion 380A strongly clamps the upper end portion of the peripheral wall 14 of the container portion 10, so that when the clamping portion 380A is engaged with the upper end portion of the peripheral wall 14 of the container portion 10, the hydrogen generating agent package 20 together with the extension portion 38 is fixed in the container portion 10. The hook portion 380 may not have the clamping portion 380A. In this case, as shown in FIG. 10(A), the distance of the U-shaped gap in the hook portion 380 is greater than the thickness of the upper end portion of the peripheral wall 14 of the container portion 10.

However, in order to ensure that the hydrogen generating agent package 20 and the extension portion 38 are fixed in the container portion 10, a lid portion 60 may be provided to cover the opening 11 of the container portion 10, as shown in Fig. 13 (A). The lid portion 60 has a lid side vent hole (or lid side opening: the same below) 60B that opens the inside of the container portion 10 to the outside. Hydrogen generated in the container portion 10 is discharged to the outside through the lid side vent hole 60B.

The hook portion 380 is hooked to the peripheral wall 14 across the upper end surface of the peripheral wall 14 of the container portion 10. Therefore, when the opening 11 of the container portion 10 is closed with the lid portion 60, as shown in FIG. 13B, the inner ceiling surface 60A of the lid portion 60 presses the hook portion 380 against the upper end surface of the peripheral wall 14 of the container portion 10. As a result, the hook portion 380 is firmly clamped between the inner ceiling surface 60A of the lid portion 60 and the upper end surface of the peripheral wall 14 of the container portion 10, and the hydrogen generating agent package 20 together with the extension portion 38 is fixed in the container portion 10. If the lid portion 60 is present, the hydrogen generating agent package 20 can be fixed in the container portion 10 together with the extension portion 38 even if the hook portion 380 does not have the clamping portion 380A.

In addition, when the extension portion 38 does not have the hook portion 380, the lid portion 60 may be configured to have a through hole 60C through which the extension portion 38 passes, as shown in FIG. 13(C). The through hole 60C penetrates the inner ceiling surface 60A of the lid portion 60 in the thickness direction of the inner ceiling surface 60A of the lid portion 60. The through hole 60C may have a size and shape that allows the extension portion 38 to pass through when inserted. However, it is preferable that the through hole 60C has a size and shape that is approximately the same as, or slightly smaller or larger than, the cross section of the extension portion 38 when cut in the thickness direction so that hydrogen generated in the container portion 10 does not leak from between the through hole 60C and the extension portion 38.

As shown in FIG. 13(D), when the lid 60 closes the opening 11 of the container 10, the extension 38 is inserted into the through hole 60C, and the upper portion 38A of the extension 38 passes through the through hole 60C and is positioned outside. In other words, when the lid 60 closes the opening 11 of the container 10, the extension 38 is divided into the upper portion (extension side external section) 38A of the extension 38 that passes through the through hole 60C and is positioned outside, and the extension side internal section 38B that is positioned inside the container 10. As a result, the extension 38 is restrained by the lid 60, and its movement is restricted. The extent to which the movement of the extension 38 is restricted is determined by the correlation between the through hole 60C and the size and shape of the extension 38.

The through hole 60C may be formed by a slit. The slit width of the slit is smaller than the thickness of the extension portion 38. If at least the area around the slit in the lid portion 60 is formed of an elastically deformable material, the slit is pushed open by the extension portion 38, and the upper portion (extension side external section) 38A of the extension portion 38 passes through the slit and is positioned outside.

27(A), the extension 38 may not have a hook 380. In this case, as shown in FIG. 27(B), when the extension 38 is inclined with respect to the container axial direction A inside the container 10, the lid side cover 60E contacts the upper end of the extension 38 and presses the extension 38 downward when the container 10 is covered with the lid 60. The lid side cover 60E refers to the portion of the lid 60 that faces the opening 11 of the container 10 and covers the opening 11. As a result, the extension 38 or the hydrogen generating agent package 20 is sandwiched between the lid side cover 60E and the bottom wall 12 and is fixed inside the container 10. The extension 38 has a length that allows the above-mentioned state. Note that it is preferable that the extension portion 38 or the hydrogen generating agent packaging 20 abuts against the peripheral wall 14 as a stopper so that the extension portion 38 does not slide along the inner bottom surface 12A and lose its position. Also, instead of the peripheral wall 14 as a stopper, a separate stopper (not shown) that protrudes from the inner bottom surface 12A may be provided on the bottom wall 12.

Sixth Embodiment
With reference to FIG. 14, the hydrogen generating device 1 in the sixth embodiment of the present invention will be described. The hydrogen generating device 1 in this embodiment includes a container portion 10, a hydrogen generating agent package 20, and an external package 40, and does not include a movement restriction portion 30. Note that the external package 40 is not depicted in FIGS. 14(A) and (B). Therefore, in the hydrogen generating device 1 in the embodiment, when liquid is poured into the container portion 10, the hydrogen generating agent package 20 floats up to the water surface as shown in FIG. 14(B). As a result, only a part of the hydrogen generating agent package 20 (the side of the hydrogen generating agent package 20 facing the inner bottom surface 12A of the container portion 10) comes into contact with the liquid, and the rest does not come into contact with the liquid and comes into contact with the outside air. Such a case is also included in the scope of the present invention. Note that the container portion 10, the hydrogen generating agent package 20, and the external package 40 are the same as those of the hydrogen generating device 1 in the first embodiment of the present invention, and therefore their description will be omitted.

As shown in FIG. 15(A), the water level W of the liquid poured into the container 10 may be equal to or lower than the plane 20A (plane facing the opening 11) on one side of the hydrogen generating agent package 20 placed on the inner bottom surface 12A of the container 10 when the inner bottom surface 12A of the container 10 is used as a reference. In other words, the water level W may be equal to or lower than the thickness of the hydrogen generating agent package 20 when the inner bottom surface 12A of the container 10 is used as a reference. In this case, the hydrogen generating agent package 20 does not float. As a result, the hydrogen generating agent package 20 maintains contact with the inner bottom surface 12A of the container 10. Even in this embodiment, the liquid can penetrate into the hydrogen generating agent package 20 and react with the hydrogen generating agent, so no problems occur in use. In particular, the embodiment shown in FIG. 15(A) is advantageous in terms of cost because a small amount of liquid is sufficient.

15(B), when the hydrogen generating agent package 20 floats up, the water level V of the liquid poured into the container 10 is preferably such that the opposing distance L between the inner bottom surface 12A of the container 10 and the flat surface 20B on the other side of the hydrogen generating agent package 20 in the container axial direction A is equal to or less than the thickness S of the hydrogen generating agent package 20 (S≧L). The embodiment shown in FIG. 15(B) has a larger contact area between the hydrogen generating agent package 20 and the liquid than the embodiment shown in FIG. 15(A), and is therefore preferable from the standpoint of hydrogen generation efficiency. Also, since only a small amount of liquid is required, it is advantageous in terms of cost.

When separating the inner bottom surface 12A of the container portion 10 from the hydrogen generating agent packaging 20 in the container axial direction A, a pair of foot members 70 may be provided on the hydrogen generating agent packaging 20 as shown in FIG. 16(A). The pair of foot members 70 are provided at a predetermined distance on a flat surface 20B on one side of the hydrogen generating agent packaging 20. The pair of foot members 70 have a base 71 and an upright portion 72. The base 71 is provided on the flat surface 20B. The upright portion 72 stands up from the flat surface 20B starting from the base 71. The upright portions 72 are provided at a predetermined distance and function as feet supporting the hydrogen generating agent packaging 20.

As shown in Fig. 16 (A), the standing portion 72 is foldably provided on the base portion 71. The base portion 71 and the standing portion 72 are integrally formed, for example, from waterproofed cardboard. The base portion 71 and the standing portion 72 are formed by making a U-shaped cut inside the rectangular cardboard.

16B, when the hydrogen generating agent package 20 provided with a pair of foot members 70 is placed on the inner bottom surface 12A of the container part 10 so that the rising portion 72 and the inner bottom surface 12A of the container part 10 are in contact with each other, the inner bottom surface 12A of the container part 10 in the container axial direction A is spaced from the hydrogen generating agent package 20. In this state, when liquid is poured into the container part 10 to the extent that the hydrogen generating agent package 20 is just immersed (water level T), the rising portion 72 comes into contact with the inner bottom surface 12A of the container part 10, and a space is formed between the hydrogen generating agent package 20 and the inner bottom surface 12A of the container part 10. In this case, the amount of liquid that reacts with the hydrogen generating agent can be increased while increasing the contact area of the hydrogen generating agent package 20 with the liquid.

It is preferable that the standing portion 72 is made of a material with a specific gravity heavier than water so that the hydrogen generating agent packaging 20 does not lose its position when liquid is poured into it. Even if the specific gravity is lighter than water, a weight (not shown) may be provided on the foot member 70 so that the specific gravity of the foot member 70 as a whole is heavier than that of water. It is also possible for the weight (not shown) to be provided on the hydrogen generating agent packaging 20.

Seventh Embodiment
A hydrogen generator 1 according to a seventh embodiment of the present invention will be described with reference to Fig. 17. The hydrogen generator 1 according to this embodiment includes a container 10, a storage unit 29, and an external packaging body 40. The container 10 and the external packaging body 40 are similar to those of the hydrogen generator 1 according to the first embodiment of the present invention, and therefore their description will be omitted. The storage unit 29 stores the hydrogen generating agent 21 inside the container 10, and has a plurality of fine vent holes 292 that allow the generated hydrogen to pass to the outside. The fine vent holes 292 are of a size that does not allow the particles of the hydrogen generating agent 21 to pass to the outside.

In this embodiment, as shown in Figs. 17(A) and (B), the storage section 29 is composed of the inner bottom surface 12A of the container section 10 and a storage side cover section 290 that covers the inner bottom surface 12A. The storage side cover section 290 covers the entire area or a part of the inner bottom surface 12A. The outer edge area 290A of the storage side cover section 290 is fixed to the inner bottom surface 12A or the inner peripheral surface 14B of the peripheral wall 14. The fixing method of the outer edge area of the storage side cover section 290 is not particularly limited. The inner area 290B inside the outer edge area 290A is not fixed to the inner bottom surface 12A. Therefore, a storage space 291 is formed between the storage side cover section 290 and the inner bottom surface 12A of the container section 10. The hydrogen generating agent 21 is stored in the storage space 291.

The storage side cover part 290 is provided with a plurality of fine vent holes 292 that allow hydrogen to pass to the outside. The fine vent holes 292 penetrate the storage side cover part 290 in the container axial direction A. Note that in FIG. 17(B), the fine vent holes 292 are drawn for the sake of explanation, but in FIG. 17(A), the fine vent holes 292 are not drawn. The fine vent holes 292 allow hydrogen generated from the hydrogen generating agent 21 to pass to the outside, but are not large enough to allow the hydrogen generating agent 21 itself to pass through, so in reality, they are difficult to see with the naked eye. In addition, the storage side cover part 290 is composed of, for example, a sheet member formed of a nonwoven fabric or a sheet member braided with fibers. In this case, the fine vent holes 292 are composed of gaps between fibers in the nonwoven fabric, or meshes of a sheet member braided with fibers. After the sheet member is placed so as to cover the inner bottom surface 12A, the outer edge region of the sheet member is fixed to the inner bottom surface 12A or the inner peripheral surface 14B of the peripheral wall 14. The method of fixing the sheet member can be various, such as heat fusion or gluing, but is not limited to a specific method. A moisture barrier layer may be provided on the surface of the accommodation side cover part 290 facing the hydrogen generating agent 21. The moisture barrier layer is similar to that described in the first embodiment, and therefore will not be described.

In the third embodiment, the hydrogen generating agent package 20 is accommodated in the storage chamber 34, but the present invention also includes an embodiment in which the storage chamber 34 is configured to accommodate the hydrogen generating agent 21 as the storage section 29. In this case, it is necessary to design the size of the multiple holes so that the hydrogen generating agent 21 does not leak out of the storage chamber 34.

In this embodiment, the hydrogen generating agent 21 is directly accommodated in the accommodation space 291 (or the accommodation space 34A of the accommodation chamber 34) provided between the accommodation side cover part 290 and the inner bottom surface 12A of the container part 10. In other words, in this embodiment, the hydrogen generating agent 21 is accommodated in the accommodation space 291 (or the accommodation space 34A of the accommodation chamber 34) so as to be in contact with the accommodation side cover part 290 and the inner bottom surface 12A of the container part 10. Therefore, in this embodiment, the accommodation part 29 appears to be integrated with the container part 10 at the inner bottom surface 12A of the container part 10. As a result, in this embodiment, when viewed from the outside, it appears as if hydrogen is generated from the inner bottom surface 12A of the container part 10. On the other hand, in other embodiments, when viewed from the outside, hydrogen appears to be generated from the hydrogen generating agent package 20 as a separate member that can be separated from the container part 10.

In addition, the insulating layer 50 may be provided in the container part 10 below the bottom wall 12 in the container axis direction A. Specifically, the lower internal space 10C is provided in the container part 10 below the bottom wall 12 in the container axis direction A. In other words, the lower internal space 10C is located below the internal space 10A in the container axis direction A. In the case of the above structure, the container part 10 has a double bottom structure in which another bottom wall 15 is provided below the bottom wall 12 in the container axis direction A. The lower internal space 10C is surrounded by the bottom wall 12, the bottom wall 15, and the peripheral wall 14. If a material constituting an insulating layer is contained in the lower internal space 10C, that part becomes the insulating layer 50. For example, air is one example of a material constituting the insulating layer. If the insulating layer 50 is provided, the degree to which heat generated during hydrogen generation is transmitted to the outside can be reduced. As a result, the user of the hydrogen generating device 1 does not feel hot even when holding it in his hand.

In this embodiment, the storage section 29 is described as being provided on the inner bottom surface 12A of the container section 10, but is not limited thereto and may be provided on the inner peripheral surface 14B of the container section 10. In this case, the storage section 29 is composed of the inner peripheral surface 14B of the container section 10 and a storage side cover section 290 that covers the inner peripheral surface 14B. In other words, the storage section 29 includes all aspects provided on the inner side surface of the container section 10.

Furthermore, the hydrogen generating agent packaging 20 and the movement restriction portion 30 in the first to fifth embodiments, and the hydrogen generating agent packaging 20 in the sixth embodiment can be regarded as a storage portion that stores the hydrogen generating agent 21 inside the container portion 10 and has a plurality of holes that allow the generated hydrogen to pass to the outside. As described above, the storage portion in this embodiment may be independent of the container portion 10, like the hydrogen generating agent packaging 20, or may be configured in cooperation with a part of the container portion 10, like the storage side cover portion 290 and the inner side bottom surface 12A. Furthermore, the hydrogen generating agent packaging 20 may simply be stored inside the container portion 10 without being constrained.

Eighth Embodiment
The hydrogen generator 1 in the eighth embodiment of the present invention will be described with reference to Fig. 18. The hydrogen generator 1 in this embodiment includes a container portion 10, a hydrogen generating agent packaging body 20 as a storage portion 29, and an outer packaging body 40. The container portion 10 and the outer packaging body 40 are similar to the hydrogen generator 1 in the first embodiment of the present invention, and therefore description thereof will be omitted.

As shown in FIG. 18A, the container part 10 has a base wall 16 that starts from the outer edge of the bottom wall 12 (external bottom surface 12B) and extends to the opposite side of the peripheral wall 14 in the container axial direction A. The base wall 16 is an annular wall that goes around the circumferential direction of the bottom wall 12 (external bottom surface 12B) along the outer edge of the bottom wall 12 (external bottom surface 12B). In this embodiment, the inner wall surface 16A of the base wall 16 and the external bottom surface 12B of the bottom wall 12 form a recess 96 that is recessed in the container axial direction A on the bottom side of the container part 10. In other words, the recess 96 is configured to be recessed in the container axial direction A on the external side (external bottom surface 12B side) of the bottom wall 12 of the container part 10. The inner wall surface 16A of the base wall 16 is the inner peripheral surface of the base wall 16, and is annular around the inner peripheral side of the base wall 16 in the circumferential direction. The outer bottom surface 12B is the surface of the bottom wall 12 opposite to the inner bottom surface 12A. The inner bottom surface 12A faces the inner space 10A side of the container part 10 or the opening 11 side, while the outer bottom surface 12B faces the outer side. In this embodiment, the recess side space 97 surrounded by the recess 96 has a size capable of accommodating the hydrogen generating agent package 20 and the liquid container 95, as shown in FIG. 18(A), for example. The outer packaging body 40 covers and packages the container part 10, the hydrogen generating agent package 20 accommodated in the recess 96, and the liquid container 95. The recess 96 is not limited to the above-mentioned embodiment, and may be any recess. 28, the recess 96 may be configured to be recessed toward the inside of the bottom wall 12, starting from the side surface 12C of the bottom wall 12. The side surface 12C of the bottom wall 12 corresponds to an outer peripheral surface about the central axis of the bottom wall 12 that is parallel to the container axial direction A. The recess 96 is recessed, for example, in an orthogonal direction E that is perpendicular to the container axial direction A.

18(B), the liquid container 95 is, for example, a bag made of a resin film, in which a liquid for generating hydrogen in reaction with the hydrogen generating agent 21 is contained, and the opening of the bag is sealed by welding or the like. The liquid container 95 is provided with a slit 95C for opening. The liquid container 95 is not limited to the above, and includes any that can contain liquid, and may be, for example, a container with a lid.

A moisture barrier layer 13 is provided on the outer bottom surface 12B. The hydrogen generating agent packaging 20 and the liquid container 95 are contained in the recessed space 97 and packaged by the outer packaging 40 so that the flat surface 20A on one side of the hydrogen generating agent packaging 20 contacts the moisture barrier layer 13, the flat surface 20B on the other side of the hydrogen generating agent packaging 20 contacts the flat surface 95A on one side of the liquid container 95, and the flat surface 95B on the other side of the liquid container 95 contacts the outer packaging 40. In this case, in order to prevent moisture from entering the hydrogen generating agent packaging 20 from the liquid container 95 side, a moisture barrier layer 82 made of a moisture-blocking material is preferably provided on the flat surface 95A on one side of the liquid container 95 (the portion facing the hydrogen generating agent packaging 20 in the container axial direction A) as shown in FIG. 18 (A).

18(C), the hydrogen generating agent packaging 20 may be accommodated in the internal space 10A of the container 10, as in the hydrogen generating device 1 in the first embodiment, and only the liquid container 95 may be accommodated in the recessed space 97. The locations of the hydrogen generating agent packaging 20 and the liquid container 95 may be interchanged. Both the hydrogen generating agent packaging 20 and the liquid container 95 may be accommodated in the internal space 10A of the container 10.

In either case, however, it is preferable that a moisture barrier layer (not shown) made of a moisture-blocking material be provided around the hydrogen generating agent packaging 20, such as the flat surface 20B on the other side of the hydrogen generating agent packaging 20, a position facing at least one of the flat surfaces 20A on one side of the hydrogen generating agent packaging 20, and a position facing the outer edge of the hydrogen generating agent packaging 20. The moisture barrier layer is provided on any one of the surfaces of the outer packaging body 40, the liquid container 95, and the container portion 10.

Ninth embodiment
A hydrogen generating device 1 in a ninth embodiment of the present invention will be described with reference to Figures 19 and 20. The hydrogen generating device 1 in this embodiment includes a container portion 10, a storage portion 29, and a lid portion 60. The container portion 10 is similar to the hydrogen generating device 1 in the first embodiment of the present invention, and therefore a description thereof will be omitted. In addition, the storage portion 29 may be any of those in the first to eighth embodiments including the hydrogen generating agent package 20.

<Lid>
The lid part 60 will be described with reference to Figures 19 and 20. The lid part 60 covers the opening (container side opening) 11 of the container part 10 to close the opening 11. The lid part 60 has a lid side cover part 61, a lid side peripheral wall part 62, a ventilation side convex part 63, a ventilation side valve part 64, and a lid side convex part 65.

As shown in Figures 20(A) and (B), the lid side cover part 61 is a part that covers the opening 11 to close the opening 11. When the lid side cover part 61 closes the opening 11 of the container part 10, the lid side cover part 61 faces the bottom wall 12 or the storage part 29 (hydrogen generating agent package 20) in the container axis direction A (depth direction of the container part 10, the same below). In this embodiment, the lid side cover part 61 is configured as an opposing wall 61A. In this embodiment, the opposing wall 61A is formed in a disk shape. The diameter of the opposing surface 61C of the opposing wall 61A on the side facing the bottom wall 12 or the storage part 29 (hydrogen generating agent package 20) (the inner diameter of the lid part 60) is preferably slightly larger than or approximately the same as the outer diameter of the end part on the opening 11 side of the container part 10.

As shown in Figures 19(B) and 20(B), the opposing wall 61A has a lid-side vent hole (or lid-side opening) 610 that connects the outside with the inside of the container part 10. The lid-side vent hole 610 penetrates the opposing wall 61A in the thickness direction of the opposing wall 61A.

The lid-side peripheral wall portion 62 is erected from the opposing wall 61A (lid-side cover portion 61) starting from the outer edge of the opposing wall 61A (lid-side cover portion 61) and extends around the circumferential direction of the outer edge of the opposing wall 61A (lid-side cover portion 61). It is preferable that the direction in which the lid-side peripheral wall portion 62 is erected is approximately parallel to the direction in which the peripheral wall 14 of the container portion 10 extends when the opening 11 of the container portion 10 is closed by the lid portion 60, or is an intersecting direction that intersects with the direction in which the peripheral wall 14 of the container portion 10 extends.

The lid-side peripheral wall portion 62 has a lid-side recess 620 on the inner peripheral side. The lid-side recess 620 is recessed in the thickness direction of the lid-side peripheral wall portion 62, starting from the inner peripheral surface 62A of the lid-side peripheral wall portion 62. The lid-side recess 620 has a shape that can fit into the container-side protrusion 14F. The container-side protrusion 14F may be configured as an annular protrusion that goes around the circumference of the peripheral wall 14 (around the container axis direction A), or may be configured as a protrusion that does not go around the circumference but extends only partially.

The lid-side peripheral wall 62 is made of an elastically deformable material. Therefore, in the process of closing the opening 11 of the container 10 with the lid 60, the lid-side peripheral wall 62 is guided by the container-side protrusion 14F, elastically deforms, and spreads radially outward of the opposing wall 61A while moving toward the bottom wall 12 of the container 10 in the container axial direction A. At this time, when the lid-side recess 620 and the container-side protrusion 14F face each other in the radial direction of the opposing wall 61A, the container-side protrusion 14F fits into the lid-side recess 620, and the lid-side peripheral wall 62 is restored and deformed radially inward of the opposing wall 61A. As a result, the lid 60 is fixed to the container 10.

The ventilation side convex portion 63 is a portion that is convex from the lid side vent 610 toward the outside (away from the opposing wall 61A (lid side cover portion 61). The ventilation side convex portion 63 has a passage 630 inside. The passage 630 penetrates the ventilation side convex portion 63 in the convex direction of the ventilation side convex portion 63 and connects to both the outside and the lid side vent 610. As a result, the internal space 10A of the container portion 10 is connected to the external space through the passage 630 and the lid side vent 610 and is open to the outside. The convex direction is a direction having a container axial direction A component. In this embodiment, the convex direction is parallel to the container axial direction A, but may be inclined with respect to the container axial direction A.

In this embodiment, the ventilation side protrusion 63 is formed in a cylindrical shape. The ventilation side protrusion 63 may be integrally formed with the opposing wall 61A as shown in FIG. 19(B) and FIG. 20(B). The ventilation side protrusion 63 may be formed by an insertion tube 640 inserted into the lid side ventilation hole 610 as shown in FIG. 21(A) and (B). The ventilation side protrusion 63 is formed by inserting the insertion tube 640 into the lid side ventilation hole 610. The insertion tube 640 is fixed to the lid side ventilation hole 610 by the clamping force of the lid side ventilation hole 610 or by another fixing means. The periphery of the insertion tube 640 is sealed by a seal member (packing) 650 on the opposing surface 61C side of the opposing wall 61A so that hydrogen does not leak from the internal space 10A through the gap between the insertion tube 640 and the lid side ventilation hole 610. The seal member (packing) 650 may be attached to the insertion tube 640 later, or may be provided in advance on the opposing surface 61C of the opposing wall 61A so as to fit during the process of inserting the insertion tube 640.

As shown in Figures 20 (A) and (B), an external tube 200 can be connected to the ventilation side protrusion 63. An example of the external tube 200 is a cannula. When the external tube 200 is connected to the ventilation side protrusion 63, the passage 630 and the internal passage of the external tube 200 are connected. As a result, the external tube 200 functions as an extension tube for the ventilation side protrusion 63.

The vent side valve 64 opens and closes the lid side vent 610 (passage 630) to the outside. In this embodiment, the vent side valve 64 is provided at the exterior side opening 631 of the passage 630 that communicates with the outside. The vent side valve 64 opens when the pressure inside the container 10 exceeds a threshold value. As shown in Figures 21 (A) and (B), the vent side valve 64 has, for example, a valve main body 64A and a spring-loaded hinge 64B.

The valve body 64A opens and closes the external opening 631 (passage 630) with the spring hinge 64B as a fulcrum. The spring hinge 64B is provided near the external opening 631 of the ventilation side protrusion 63. The spring hinge 64B biases the valve body 64A in the direction of closing. In a range in which the pressure inside the container 10 does not exceed a predetermined threshold, the biasing force of the spring hinge 64B exceeds the pressure inside the container 10, and the spring hinge 64B maintains a posture in which the external opening 631 (passage 630) is closed. On the other hand, when the pressure inside the container 10 exceeds a predetermined threshold due to the generation of hydrogen, the spring hinge 64B is pressed in the opening direction by the pressure inside the container 10. As a result, the internal space 10A of the container 10 is opened to the outside, and the generated hydrogen flows to the outside.

The vent valve section 64 may also include a position maintaining mechanism (not shown) that maintains the position in which the valve body section 64A forcibly opens the exterior opening 631 (passage 630) to the outside. The position maintaining mechanism may be configured to fix the valve body section 64A in an open position, or may be configured to regulate the biasing force of the spring of the spring hinge 64B, for example.

The vent side protrusion 63 may not be present. In a configuration without the vent side protrusion 63, hydrogen is discharged to the outside through the lid side vent 610. In a configuration without the vent side protrusion 63, a valve portion (not shown) that opens and closes the lid side vent 610 is provided in the lid side vent 610. This valve portion has a structure similar to that of the vent side valve portion 64. The present invention also includes configurations in which the vent side valve portion 64 and a valve portion (not shown) that opens and closes the lid side vent 610 are not provided.

When the vent valve section 64 is provided, it is possible to limit the discharge of unnecessary hydrogen from the inside of the container section 10 to the outside. In addition, by adding a position maintaining mechanism (not shown) to the vent valve section 64, it is possible to discharge hydrogen from the inside of the container section 10 to the outside whenever the user wishes to inhale hydrogen.

In this embodiment, the lid-side protrusion 65 is formed by a ring-shaped wall that starts from the outer side surface 61B of the opposing wall 61A (lid-side cover portion 61) facing the outside of the container portion 10 and protrudes away from the opposing wall 61A, and goes around the outer side surface 61B along the outer side surface 61B. The lid-side protrusion 65 is protruded in a direction having a container axial direction A component. In this embodiment, the lid-side protrusion 65 is formed as a cylindrical wall 65A extending in the container axial direction A, as shown in FIG. 19 (A). The space 600 surrounded by the inner wall surface 65B of the cylindrical wall 65A and the outer side surface 61B has a size that can accommodate the hydrogen generating agent package 20 and/or the liquid container 95. In addition, when looking at the inner peripheral side of the lid-side protrusion 65, it can be seen that a lid-side recess 65F is formed. In other words, the lid-side protrusion 65 can be seen to have a lid-side recess 65F that is open to the outside on the inner side. The space surrounded by the lid-side recess 65F corresponds to the space 600. The hydrogen generating agent package 20 and/or the liquid container 95 are placed so that at least a part of their flat surface abuts against the outer side surface 61B. The hydrogen generating agent package 20 and/or the liquid container 95 are preferably accommodated so as not to protrude from the space 600 even if the effective overall length is reduced by folding or curving the hydrogen generating agent package 20 and/or the liquid container 95. Taking these factors into consideration, the shape and size of the space 600 (the height and inner diameter of the cylindrical wall 65A) are determined.

In this embodiment, the lid side ventilation hole 610 and the ventilation side protrusion 63 are provided on the outer side surface 61B so as to be aligned outside the space 600 and in parallel with the lid side protrusion 65, as shown in FIG. 22(A), but are not limited thereto. For example, as shown in FIG. 22(B), the lid side ventilation hole 610 and the ventilation side protrusion 63 may be provided on the outer side surface 61B in the space 600 surrounded by the lid side protrusion 65. Also, for example, as shown in FIG. 22(C), the lid side protrusion 65 may be configured as an arc wall 65C provided in an arc shape rather than an annular shape. Also, as shown in FIG. 22(D), the lid side protrusion 65 may be configured by two discontinuous arc walls 65D and 65E. Also, for example, as shown in FIG. 22(E), the lid side protrusion 65 may be a polygonal tube shape, including a square tube shape, instead of a cylindrical shape.

The lid side protrusion 65 is not limited to the arc walls 65C to 65E or the polygonal cylinder. In other words, the lid side protrusion 65 is convex starting from the external side surface 61B of the lid side cover part 61 facing the outside of the container part 10, and extends continuously or discontinuously on the external side surface 61B along the external side surface 61B so that the space 600 surrounded by the lid side protrusion 65 is formed. Therefore, the lid side protrusion 65 may be, for example, a curved surface whose inner circumferential surface goes around continuously or discontinuously. The lid side protrusion 65 may also be, for example, a plane whose inner circumferential surface goes around continuously with adjacent planes intersecting, or a plane whose inner circumferential surface goes around discontinuously in a state in which the extensions of adjacent planes may intersect. The lid side protrusion 65 may also be, for example, a curved surface whose inner circumferential surface does not go around but forms the surrounding space 600, or a discontinuous curved surface. The lid-side protrusion 65 may be, for example, a plane in which the inner circumferential surface forms the surrounding space 600 without going all the way around, and adjacent planes intersect and are continuous, or a discontinuous plane in which the inner circumferential surface forms the surrounding space 600 without going all the way around, and extended planes of adjacent planes may intersect. Various combinations of the above-mentioned aspects of the lid-side vent 610, the vent-side protrusion 63, and the lid-side protrusion 65 are also included in the scope of the present invention.

<Operation of hydrogen generator>
The operation of the hydrogen generating device 1 in this embodiment will be described with reference to Figures 19 and 20. In the state shown in Figures 19(A) and (B), the hydrogen generating agent package 20 accommodated in the space 600 surrounded by the lid-side convex portion 65 (or the lid-side concave portion 65F) is taken out and placed inside the container portion 10, and the hydrogen generating agent package 20 is placed on the inside bottom surface 12A of the container portion 10. Then, liquid is poured into the inside of the container portion 10. At this time, as shown in Figures 20(A) and (B), for example, the water level W is set to a level at which the entire hydrogen generating agent package 20 is immersed or less. In other words, the water level W is about the thickness of the hydrogen generating agent package 20 based on the inside bottom surface 12A of the container portion 10. It should be noted that more liquid may be poured. The container portion 10 is covered with the lid portion 60.

If the vent valve 64 is not provided, when hydrogen is generated by reaction between the liquid and the hydrogen generating agent, the hydrogen passes through the lid vent 610 of the lid 60 and the passage 630, and is discharged to the outside from the exterior opening 631 of the vent protrusion 63. The user inhales the hydrogen. This allows the user to efficiently take in hydrogen into the body.

On the other hand, when the vent side valve section 64 is provided, hydrogen accumulates in the internal space 10A of the container section 10 with the vent side valve section 64 closing the passage 630. Then, when the pressure in the internal space 10A of the container section 10 exceeds a predetermined threshold due to hydrogen, the vent side valve section 64 opens the external side opening 631 (passage 630) to the outside. Note that when the vent side valve section 64 is provided, the vent side valve section 64 may close the passage 630 when the user wants to inhale hydrogen, so when the user wants to inhale hydrogen, the vent side valve section 64 can be forced to open the external side opening 631 (passage 630) to the outside by a posture maintaining mechanism (not shown).

Tenth Embodiment
The hydrogen generating device 1 in the tenth embodiment of the present invention will be described with reference to Fig. 23. As shown in Fig. 23(A), the hydrogen generating device 1 in this embodiment is obtained by adding a storage section 80 to the hydrogen generating device 1 in the first embodiment.

The storage unit 80 has a storage space 800 therein for storing gas (hydrogen) discharged to the outside through the passage 630 of the ventilation side protrusion 63. The storage unit 80 has a connection part 81 that can be detachably connected to the ventilation side protrusion 63 so that the storage space 800 and the space in the passage 630 are connected to each other. The connection part 81 is composed of a first storage side protrusion 83 that is convex starting from the first storage side hole 80A provided in the storage unit 80. The first storage side protrusion 83 is composed of, for example, a tube having an insertion path 830 that penetrates in a convex direction inside itself. The ventilation side protrusion 63 is configured to be able to be inserted into the insertion path 830 while being in close contact with the insertion path 830. In other words, the shape and size of the first storage side protrusion 83 and the ventilation side protrusion 63 are configured so that hydrogen does not leak to the outside from the connection part between the first storage side protrusion 83 and the ventilation side protrusion 63. Furthermore, a fixing portion (not shown) may be provided to maintain the state in which the first storage side protrusion 83 is inserted into the ventilation side protrusion 63. The storage portion 80 as described above is, for example, configured by a bag body. The bag body is preferably configured by a material that can contract and expand (scale up and down). Examples of such materials include resin such as vinyl, paper, and the like.

Hydrogen generated from the hydrogen generating agent packaging body 20 (storage section 29) within the container section 10 is discharged to the outside through the passage 630, but by connecting the storage section 80 to the ventilation side protrusion 63, it is possible to store a certain amount of hydrogen that would normally be released into the atmosphere and wasted.

23B, a second storage side hole 80B may be provided separately in the storage section 80, and a second storage side convex section 84 having a passage 840 therein may be provided starting from the second storage side hole 80B. The passage 840 penetrates the second storage side convex section 84 in a convex direction. The insertion path 830 and the passage 840, the first storage side hole 80A and the second storage side hole 80B are generally configured similarly to the ventilation side convex section 63. Hydrogen in the storage space 800 is discharged to the outside through the passage 840. At this time, if the pressure in the storage space 800 becomes too high due to the hydrogen stored in the storage section 80, there is a risk that the storage section 80 will burst, so a storage side valve 85 that opens and closes the passage 840 may be provided.

The storage side valve 85 is provided at the external side opening 841 of the passage 840 that communicates with the outside. The storage side valve 85 opens when the pressure inside the storage section 80 (storage space 800) exceeds a threshold value. The structure of the storage side valve 85 is similar to that of the vent side valve section 64. In the case of a configuration without the second storage side protrusion 84, a valve (not shown) that opens and closes the second storage side hole section 80B is provided in the second storage side hole section 80B.

Eleventh Embodiment
The hydrogen generator 1 in the eleventh embodiment of the present invention will be described with reference to Fig. 24. As shown in Fig. 24(A), the hydrogen generator 1 in this embodiment is configured such that a lid-side insertion hole 660 separate from the lid-side ventilation hole 610 is provided in the opposing wall 61A (lid-side cover portion 61) of the hydrogen generator 1 in the first embodiment.

The lid-side insertion hole 660, like the lid-side vent hole 610, penetrates the opposing wall 61A in the thickness direction of the opposing wall 61A, and connects the outside to the inside of the container part 10. The lid-side insertion hole 660 has a size and shape that allows an external tube to be inserted.

The lid-side insertion hole 660 is provided with an insertion-side valve portion 661 on the inside of the container portion 10. The insertion-side valve portion 661 opens when a pressing force equal to or greater than a predetermined threshold is applied from the outside toward the inside of the container portion 10. Specifically, the insertion-side valve portion 661 opens when pressed with a predetermined pressing force (a force equivalent to a predetermined threshold) by a tube inserted into the lid-side insertion hole 660. On the other hand, the insertion-side valve portion 661 is configured not to open with a force from the inside of the container portion 10 toward the outside. In other words, the insertion-side valve portion 661 functions as a check valve. The specific configuration of the insertion-side valve portion 661 is the same as that of the vent-side valve portion 64 (valve body portion and spring-loaded hinge), so the description of the vent-side valve portion 64 is also applicable here.

<Hydrogen-containing water production device and production method>
A hydrogen-containing water producing device capable of producing hydrogen-containing water can be configured using the hydrogen generating device 1 in this embodiment. The hydrogen-containing water producing device will be described below with reference to Fig. 25. The hydrogen-containing water producing device includes a hydrogen generating device 1 on the hydrogen generating side that generates hydrogen, a container part 10 and a lid part 60 on the hydrogen receiving side that receives the generated hydrogen, and an air pipe 90 that connects the hydrogen generating side and the hydrogen receiving side.

First, as shown in FIG. 25(A), water is poured into the hydrogen receiving container 10 (right side of FIG. 25(A)). Then, one end 90A of the vent pipe 90 is inserted into the lid side insertion hole 660 of the lid 60 of the hydrogen generating device 1 on the hydrogen generating side (left side of FIG. 25(A)) to connect it to the hydrogen generating device 1 on the hydrogen generating side. Note that, as shown in FIG. 25(B), one end 90A of the vent pipe 90 may be inserted directly into the vent side protrusion 63, instead of the lid side insertion hole 660. In addition, when the lid 60 in the ninth embodiment is applied to the hydrogen receiving container 10, the lid side insertion hole 660 is removed from FIG. 25(B). Such a configuration is also included in the scope of the present invention.

The other end 90B of the vent pipe 90 is inserted into the lid-side insertion hole 660 in the lid portion 60 on the hydrogen-receiving side to connect it to the lid portion 60. At this time, the vent pipe 90 is inserted until the other end 90B of the vent pipe 50 is positioned near the inner bottom surface 12A of the container portion 10 on the hydrogen-receiving side. The other end 90B of the vent pipe 90 may be inserted into the vent-side protrusion 63. Such configurations are also within the scope of the present invention.

In this state, water is poured into the container 10 of the hydrogen generating device 1 on the hydrogen generating side, and the hydrogen generating agent package 20 is reacted with the hydrogen generating agent. As a result, hydrogen is generated and moves to the container 10 on the hydrogen receiving side through the vent pipe 90. The hydrogen is discharged from the other end 90B of the vent pipe 50 into the water inside the container 10 on the hydrogen receiving side. During this process, the hydrogen dissolves in the water inside the container 10 on the hydrogen receiving side. The undissolved hydrogen is discharged to the outside through the lid side vent 610 of the lid 60 on the hydrogen receiving side and the passage 630 of the vent side protrusion 63.

As described above, while hydrogen is moving through the vent pipe 90 to the hydrogen receiving container 10, hydrogen can be discharged to the outside through the passage 630 of the vent side protrusion 63 in the hydrogen generating device 1 on the hydrogen generating side. In other words, with the hydrogen generating device 1 in this embodiment, the user can inhale hydrogen while producing hydrogen-containing water.

In addition, in the hydrogen-containing water production device, one end 90A of the vent pipe 90 may be inserted into the vent side protrusion 63 of the hydrogen generator 1 on the hydrogen generation side. Also, in the hydrogen-containing water production device, it is sufficient that the hydrogen generator 1 on the hydrogen generation side is provided with only one of the vent side protrusion 63 and the lid side insertion hole 660.

<Twelfth embodiment>
The hydrogen generating device 1 in the twelfth embodiment of the present invention will be described with reference to Fig. 26. As shown in Fig. 26, the hydrogen generating device 1 in this embodiment can accommodate not only the hydrogen generating agent package 20 but also a liquid container 95 in a space 600 surrounded by an inner wall surface 65B of the cylindrical wall 65A of the hydrogen generating device 1 in the first embodiment and an outer side surface 61B of the opposing wall 61A.

The liquid container 95 is the same as that described in the eighth embodiment (see FIG. 18B). That is, the liquid container 95 is, for example, a bag made of a resin film in which liquid is contained, and the mouth of the bag is sealed by welding or the like. The liquid container 95 is provided with a slit 95C for opening. Note that the liquid container 95 is not limited to the above, and includes any that can contain liquid, and may be, for example, a container with a lid.

In the hydrogen generating device 1 in this embodiment, the hydrogen generating agent package 20 and the liquid container 95 are stacked on the outer side surface 61B of the opposing wall 61A along the container axial direction A and are contained in a space 600 surrounded by a cylindrical wall 65A. Note that the scope of the present invention also includes an embodiment in which only the liquid container 95 is contained in the space 600.

Thirteenth Embodiment
The hydrogen generating device 1 in the thirteenth embodiment of the present invention will be described with reference to Figures 29 and 30. As shown in Figure 29(A), the hydrogen generating device 1 in this embodiment is the hydrogen generating device 1 in the ninth embodiment of the present invention (see Figure 19) provided with a container side filter 18, a lid side air hole filter 18A, a container side window 19, and a lid side window 19A.

<Filter>
When the hydrogen generating agent and the liquid react in the container 10, hydrogen is generated. At this time, hydrogen bubbles may burst when they jump out from the liquid surface, and the liquid may scatter in the form of a lump of a predetermined size. Furthermore, when the scattered lump of liquid passes through the passage 630 of the ventilation side convex portion 63 and jumps out to the outside, the lump of liquid may reach the user of the hydrogen generating device 1. The container side filter 18 is provided to capture the scattered lump of liquid before it jumps out to the outside. For this reason, the container side filter 18 is capable of capturing the lump of liquid that is scattered with the generation of hydrogen, but is made of a material having a filter side vent (mesh) large enough to pass the hydrogen-containing gas generated from the hydrogen generating agent 21. Examples of such materials include nonwoven fabric, but are not limited to this, and other materials may also be used.

The scattered liquid mass passes through the passage 630 of the ventilation side protrusion 63 and is thrown out to the outside. For this reason, the container side filter 18 is disposed at a position on the path through which the scattered liquid mass passes from the inner bottom surface 12A of the bottom wall 12 of the container part 10 to the passage 630, as shown in Figures 29 (A) and (B). Specifically, the container side filter 18 is disposed, for example, in the container part 10 at a position spaced apart by a predetermined height K in the container axis direction A from the inner bottom surface 12A of the container part 10. The container side filter 18 is configured to extend over the entire area surrounded by the inner circumference at that position. For this reason, the container side filter 18 divides the internal space 10A of the container part 10 in the container axis direction A in two at that position. In other words, the container side filter 18 divides the internal space 10A into an opening proximal side space 10D and an opening distal side space 10E. When the container side filter 18 is provided in this manner, the container side filter 18 blocks all paths of the splashed liquid mass at that position, and all of the splashed liquid mass is captured by the container side filter 18.

In addition, the container-side filter 18 may extend to a part of the area surrounded by the inner circumference at the above position. In this case, it is preferable that the container-side filter 18 extends to an area of the above area closer to the lid-side vent 610 than the center.

The lid-side air vent filter 18A is provided to block and cover the opening 610A on the back side of the lid 60 in the lid-side air vent 610. As a result, a lump of liquid that splashes toward the lid-side air vent 610 is captured by the lid-side air vent filter 18A and cannot pass through the lid-side air vent 610.

Furthermore, a lid-side passage filter (not shown) made of the same material as the container-side filter 18 and the lid-side vent filter 18A and having a filter-side vent (second filter-side vent) configured in the same manner as the lid-side vent filter 18A may be provided at any position along the passage 630 or to block and cover the exterior-side opening 631 of the passage 630. If provided in this manner, it is possible to prevent the splashed liquid mass from flying out to the outside.

At least one of the container side filter 18, the lid side vent filter 18A, and the lid side passage filter may be provided. However, since providing the lid side vent filter 18A or the lid side passage filter is easier in terms of manufacturing than providing the container side filter 18, providing the lid side vent filter 18A or the lid side passage filter can be manufactured at a lower cost.

<Window section>
The container-side window 19 is made of a transparent material and is provided so as to form a partial area of the peripheral wall 14 of the container part 10. Since the container-side window 19 is made of a transparent material, a user of the hydrogen generating device 1 can see the inside of the container part 10 from the outside through the container-side window 19, as shown in FIG.

The container side window 19 is provided to allow the user of the hydrogen generator 1 to see the hydrogen generated. The hydrogen generated can be confirmed as bubbles inside the liquid. For this reason, it is preferable to provide the container side window 19 in an area where the liquid can be seen. Examples of such areas include an area that starts from the lowest end of the peripheral wall 14 or its vicinity, spreads in the container axial direction A toward the opening 11, and spreads in the circumferential direction of the peripheral wall 14, but is not limited to this. In other words, as long as bubbles inside the liquid can be confirmed through the container side window 19, the container side window 19 may be provided at any position on the peripheral wall 14. For example, if the liquid level in the container part 10 is low, it is preferable that the container side window 19 be provided as close as possible to the lowest end of the peripheral wall 14, and if the liquid level in the container part 10 is high, it generally does not matter where the container side window 19 is provided.

The entire container portion 10 may be made of a transparent material. In this case, the entire container portion 10 can be considered to constitute the container side window portion 19.

The lid side window 19A is made of a transparent material and is provided so as to form a partial area of the lid side cover portion 61 of the lid portion 60. And, because the lid side window 19A is made of a transparent material, the user of the hydrogen generator 1 can see the inside of the container portion 10 from the outside through the lid side window 19A, as shown in FIG. 30.

The lid-side window 19A, like the container-side window 19, is provided to allow the user of the hydrogen generator 1 to see the hydrogen being generated. Because the lid-side window 19A allows the entire liquid to be viewed from above the liquid, the hydrogen bubbles being generated can be confirmed no matter where the lid-side window 19A is provided on the lid-side cover 61.

In addition, the entire lid portion 60 or the entire lid side cover portion 61 may be made of a transparent material. In this case, the entire lid portion 60 or the entire lid side cover portion 61 can be considered to constitute the lid side window portion 19A.

In this embodiment, both the container side window portion 19 and the lid side window portion 19A are provided, but this is not limited to this and only one of them may be provided.

The hydrogen generator of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. In addition, the present invention also includes hydrogen generators, containers, and lids that are constructed by arbitrarily combining the components in the first embodiment to the thirteenth embodiment.

The hydrogen generating device of the present invention can be configured by housing a nonwoven fabric bag containing a hydrogen generating agent (hydrogen generating agent packaging body 20) in a paper or plastic cup (container 10). The bag is placed on the inside bottom surface of the cup. The hydrogen generating device of the present invention may also be configured by attaching a nonwoven fabric sheet around the outer edge of the inside bottom surface of a paper or transparent plastic cup (container 10). The hydrogen generating agent is housed between the inside bottom surface and the nonwoven fabric sheet. The above-mentioned hydrogen generating device is sold at convenience stores, and hydrogen is generated simply by pouring water into the cup. The user inhales the generated hydrogen for health reasons through the lid side ventilation hole 610 or the ventilation side protrusion 63.
